Chris,
Basically what you are proposing  IS a spark gap TC -albeit one where the
tank capacitor is charged by an inverter; it is practically the same as
using a electronic NST to
charge the tank capacitor -and the same problem would presumably apply
i.e. it would not be possible  to store enough joules in the capacitor
without having to supply an enormous number of VA together with a massive
circulation current at the high frequency of the inverter.

With 50 or  60 Hz mains frequency the VA together with circulating current
much smaller and more manageable.

A possible solution -which should also work with an electronic NST- would be
rectify the output of the inverter to DC and
use that to charge the capacitor - fast diodes capable of working at high
voltages would be required as ordinary high voltage diodes like 1N4007 would
be much too slow.
